2 Meter Beam Element Question
 

Which is more practical?
Driven element with two directors or reflector, driven element,
director.

IMHO, it depends on what you want the Reflector modifies the dipole
pattern to a given direction. A dipole-director favors a direction but
still has more gain on the side with the director.

Neither one is worth building at 2 meters. A 5 element beam with a
reflector, driven element. and 3 directors could be built on a 4 - 5 foot
boom.

Tam's totaly correct in that. I tried it, only to find that a three
elemnt yagi performs a whole lot less than a silly J-Pole does on 2
meters. That, and your modulation drops out the bottom for some reason
too. 5 elements or more. Fewer elements is just a wast of your time,
effort, and money.
Also, a cheap TeeVee rotor will work very well on such a small yagi
like that!

There was something wrong with that yagi then... Seriously..

A 3 el NBS yagi gives appx 9.4 dbi gain. How is that a waste of time
effort or money? The difference between a good 3 el, and a good 5 el
are not all that large. I have a 3 el yagi for FM mounted vertical. I
hear
stuff on that thing that doesn't exist on a vertical.
This is not to say more elements are not worth the trouble. They
usually
are. But if you have a 3 el that gets smoked by a lousy J-pole,
Houston , we have a problem.
